DNS / MX Record Issue?

Post by mmicha » Wed Dec 14, 2011 10:23 am


I am doing a lab with Microsoft Exchange. I use roller networks for dns and smarthost relaying...

I've currently got 3 domains setup at Roller Networks. 2 of the 3 domains are able to send and recieve mail fine. However, the third domain called mindfluxer.com keeps getting rejected in the logs saying something like "no resolvable mx record". I've set this domain up exactly like the others, as well as deleted everything and recreated it.

Is there something wrong on RN side? Am I in violation of something? I'm pretty stumped right now with this.

It looks fine on a direct query, but our caches have a cached result that is different for at least the next 25 minutes. Hosting DNS on our own Primary or Secondary DNS does not short-circuit the normal DNS lookup process. There's a longer explanation here:

You can also query our caching DNS resolvers for MX records with the mail test tools:
